In the automotive industry, everyone realizes that semiconductors and software are the new engines of automotive technology, and the current trend towards electric vehicles is very good for us. Because we have a small business share in the key power systems of fuel vehicles, while in the electric vehicle market, the opposite is true. "ADI CEO Vincent Roche said in a conference call in 2022.

In the automotive industry, everyone realizes that semiconductors and software are the new engines of automotive technology, and the current trend towards electric vehicles is very good for us. Because we have a small business share in the key power systems of fuel vehicles, while in the electric vehicle market, the opposite is true. "ADI CEO Vincent Roche said in a conference call in 2022.

He mentioned three core technologies and rapidly growing businesses in the ADI automotive electronics field, including battery management (BMS), audio processing and audio linking, and data and video connectivity.

Recently, at the Shanghai Electronics Show in Munich, Chen Sheng, the Marketing Director of ADI's Asia Pacific Automotive Business, and Shen Fei, the Technical Marketing Director of ADI's China Automotive Electronics Business Unit, detailed ADI's new technologies in these three major fields and the contributions made by the China Business Unit.

How to grow the battery management business from small to large

40% of the price of electric vehicles depends on the battery, and the Battery management system is the key to determine the health and safety of the battery. It is responsible for monitoring and managing the charging status and health status of multiple battery strings. For the high-voltage battery pack of electric vehicles, accurate monitoring of each battery unit and the entire battery pack parameters is crucial to ensuring the driving range, safety, and reliability of electric vehicles.

Linglilte is the first company in the industry to launch battery management technology and wireless battery management technology. In 2008, the company developed an integrated high-voltage battery stack monitor, and later launched the industry's first wireless Battery management system. ADI acquired Linglaite in 2017 and then acquired Meixin in 2020. By integrating several companies' BMS systems, ADI has now launched its seventh generation BMS products.

At the time of acquiring Lingleite, the ADI BMS business had an annual business volume of approximately $50 million, and with the development of new energy vehicles, it is expected to reach $1 billion in the coming years.

According to data released on Investor Day in 2022, ADI has provided BMS systems for millions of electric vehicles, and 16 of the top 20 electric vehicle OEMs worldwide are customers of ADI.

Chen Sheng also specifically mentioned wireless BMS technology, which has the advantages of saving cables, improving scalability, and simplifying assembly compared to wired transmission.

Moreover, the reliability of the wireless BMS has also been widely verified. At present, the universal modular battery platform Otronic has taken the lead in adopting ADI's wireless Battery management system. Kent Helfrich, Executive Director of Global Electrification and Battery Systems at General Motors, stated in a press release in September 2020 that "scalability and reducing complexity are the themes of our Ultrium batteries - wireless management systems are a key driving force for this amazing flexibility.
